This invention relates to a setting gauge for corner beads and isdesigned to assist a plasterer in making window recesses which areperfectly square and plumb.

In practice, after the Window frames are set and it is desired to applylath, it is conventional to provide corner beads, particularly at thecorners of the window recesses. After the corner beads and the lath arein place, the plasterers proceed with their plastering, and the windowrecesses will be square and plumb if the corner bead is square andplumb. The preliminary operation of squaring up and making plumb acorner bead is a rather tricky operation requiring a considerable amountof skill and taking a skilled workman perhaps a half hour.

It is an object of my invention to provide a simple setting gaugewhereby even an unskilled workman can insure that a corner bead issquare and plumb and can complete the setting of a corner bead in aboutten minutes.

It is a further object of my invention to provide a device as outlinedabove which will be simple in operation and inexpensive in constructionand convenient in use.

These and other objects of my invention which I shall point out in moredetail hereinafter or which will be apparent to one skilled in the artupon reading these specifications, I accomplish by that certainconstruction and arrangement of parts of which I shall now describe anexemplary embodiment.

Reference may be had to the drawings forming a part hereof and in which:

Fig. 1 is a plan view of the device.

Fig. 2 is an elevational view as seen from the top of Fig. 1.

Fig. 3 is an elevational view as seen from the left of Fig. 1.

Fig. 4 is a partial cross sectional view taken on the line 4, 4 of Fig.1 on an enlarged scale.

Fig. 5 is a detailed partial bottom view of Fig. 1.

Fig. 6 is a partial horizontal cross sectional view of a buildingstructure showing the device in use.

Briefly, in the practice of my invention, I provide a square comprisingthe shorter arm I which is preferably of a hard wood and the long arm IIwhich may be of sheet metal and which is provided with the longitudinalslot l2. The member II is held in a slot in the member 10 as by means ofrivets I 3. The member I l is provided with a small extension l4 havingan edge l which is a continuation of the edge 16 of the member II. Asquare member indicated generally at IT is arranged to slide along themember II as follows: a plate I8 is provided with a narrow portion I9arranged to fit in the slot l2 and carries integral therewith a bolt 20;a plate 2! having a turned edge 22 fits over the bolt 20 and the entireassembly is held in place by means of a wing nut 23. It will be clearthat by loosening the wing nut, the assembly I! may be adjustedlongitudinally of the member II. By referring to Fig. 5, it will benoted that the member 17 carries a notch 24 adjacent the edge II. On theface of the member l1, visible in Fig. 1, there is carried a clamparrangement indicated generally at 25. The member 25 consists of a pairof crossed arms having finger grip members 26 urged apart by acompression spring 21. The other ends of the crossed arms are providedwith hook like gripping elements 28 which are arranged to be positionedin alignment with the notch 24. The member 25 may be bolted to themember I! as at 29 or suitably attached in any desired manner.

The use of the device will be clear from a consideration of Fig. 6 whereI have shown a window frame element 39 and a wall structure indicatedgenerally at 3|. A corner bead of conventional type is indicated at 32.It is desired that the bead portion 33 be on a continuation of thewindow frame edge, indicated at 34. Thus, the square is positioned asshown with the edge l5 engaging the edge 34. The edge It thus forms acontinuation of the edge 34 and square with the plane of the window byvirtue of the fact that members [0 and II define an accurate rightangle. The member I! may now be adjusted to the proper position and thebead 33 may be engaged in the slot 24 by the member 25. If the devicefits as shown in the drawing, the plasterer will know that the bead 33is square with the window frame and he may nail the corner bead 32 tothe stud at this point. He may then slide the square down with themember 25 still in engagement with the bead and place the portion [3against the next lower cross bar of the window and check that the cornerbead is plumb. If it is not, he can bend it or slide it by hand until itis, and then nail it at that point. He repeats this procedure all theway down and when he has finished he is sure that the corner bead whichis to be his plastering guide is both square with the window frame andplumb.

With the device above described even an unskilled worker can producework which is square and plumb after a minimum of instruction and inabout one third the time that has heretofore been necessary for askilled worker.

It will be clear that numerous modifications may be made withoutdeparting from the spirit of my invention and I therefore do not intendto limit myself except as pointed out in the claims which follow.

Having now fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. A setting gauge for corner beads comprising two arms having edgesdefining a right angle, a gauge member having an edge slidable on one ofsaid arms, and. means mounted on said gauge member for gripping of acorner bead. i

2. A setting gauge for corner beads comprising a shorter arm and alonger am, said arms having edges defining a right angle, a gauge memberslid able on said longer arm, and means mounted on said gauge member forgripping a corner head.

3. A setting gauge for corner beads comprising a longer arm and ashorter arm, said arms having edges defining a right angle, a gaugemember slidabl'e on said longer arm, and a notch in said gauge membertangent to the edge of said longer arm for defining the position of acorner bead.

4. A setting gauge for corner beads comprising a longer arm and ashorter arm, said arms having edges defining a right angle, a gaugemember slidable on said longer arm, a notch in said gauge member tangentto the edge of said longer arm, and means associatedwith said notch forgripping and holding in said notch a corner bead.

5-. A device according to claim 4 in which said gripping means comprisesa pair of crossed arms pivoted to said gauge member, said armsconstituting gripping jaws disposed adjacent said notch, and means foryieldingly urging said jaws to ether.

6. A device according to claim 3 in which one of said arms has anextension pastsaid other arm, said extension havin an inner edge inalignment with the outer edge of said arm.

7. A setting gauge for comer beads comprising two arms having edgesdefining a,- right' angle, one of said arms having an erltension pastsaid other arm, said extension havin an inner edge in alignment with theouter edge of said first mentioned arm, a slot in said first mentionedarm, a gauge member sl'idable in said slot and having means for lookingit in desired position, a notch in the edge of said gauge member tangentto the edge of said slotted arm, and grippin means associated with saidnotch, said gripping means comprising a pair of crossed arms pivoted tosaid gauge member, said arms constituting gripping jaws adjacent saidnotch,- and means for yieldin'gliz urgin said jaws. together,
